According to iteration theory they set preset value in the deformation of steel structure construction adjust the building configuration in the construction process.Besides by imposing or uninstalling the force with jack authors adjust the whole configuration and internal stress of building.In this way it achieves free stress condition in the installation process and ensures the geometry of the body and the stress state to consistent with theoretical design value. Key words:tall buildings;suspension structures;tubular structures;stress control;simulation;iteration 悬挂式建筑作为一种新兴的建筑形式具有造型的现代楼宇设计，室外空间利用山地高差以及设 型新颖占地面积小并能减小地震作用等诸多优 置叠落式的大水景，形成景观式的建筑物...
